How to install Git in Lubuntu (APT is "Unable to locate package
libcur14-gnutls-dev")?

I've tried to install git to my laptop which runs lubuntu.I followed the
pattern on git website and it says :
To install Git, you need to have the following libraries that Git depends
on: curl, zlib, openssl, expat, and libiconv
$ apt-get install libcurl4-gnutls-dev libexpat1-dev gettext \
libz-dev libssl-dev
However when I typed it, I got this :
gwapps@gwapps-ThinkPad-X61:~$ sudo apt-get install libcur14-gnutls-dev
libexpat1-dev gettext libz-dev libssl-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'zlib1g-dev' instead of 'libz-dev'
E: Unable to locate package libcur14-gnutls-dev
gwapps@gwapps-ThinkPad-X61:~$
Does anyone know what is wrong and what should I do?
